Individuals and teams fan out across the state for a frenzied 24 hours, trying to spot as many bird species as possible. As it is a key migration time of the year, New Jersey is the focal point for flocking birds that disappear off the Jersey landscape just days or weeks later.

If you are a pro, or even a novice, birder, you will do whatever you can over this 24-hour, statewide event to capture that little edge, finding every type of bird possible, while helping raise money for New Jersey Audubon.

Birders — which can be a surprisingly competitive bunch — are now implementing the latest technologies. That includes the use of GPS and social media, fueled by smartphones and tablets, as well as WiFi hotspots that can reach into the densest New Jersey forests.

“So much has changed in the world of birding in the last 35 years,” said Pete Dunne, a naturalist, author and founder of the World Series of Birding. He has seen it all, scouring the state in the darkest hours of night, listening for the sounds of the rarest birds.

Everything from registration, to route planning, to equipment has evolved at the World Series of Birding, he said. Gone are pencils and clipboards. Forget the old paper maps, and asking the guy at the roadside gas station for directions.

Birding is clearly a 21st-century sport.

“But the core of the event — gathering, learning and competing with others who love birds and the environment — is still the same,” said Dunne, who serves as New Jersey Audubon’s Birding Ambassador.

For the past three years, New Jersey Audubon has produced and invited teams to use an app that has revolutionized not only the way teams keep track of their lists of birds spotted, but also the way in which teams relate to each other during the 24-hour mega-event.

On May 12, New Jersey Audubon will fully roll out its new app, and hundreds of participants will be using it.

Dr. David La Puma, Director of New Jersey Audubon’s Cape May Bird Observatory, explains the significance.

“Using the app, teams record and submit their sightings all day long. If they submit a bird that isn’t supposed to be where they found it, they can send a picture to verify it in real time,” La Puma said.

“The best part — by the time teams come in at the end of the day — their lists are tallied, verified and the results are posted,” he said. “There’s no more staying up until 3 a.m. to do data entry!”

It is also impossible for birders to claim to see, for example, a Dodo bird this year, as a team of experts monitors identifications in real time. If a team claims to see a questionable bird, they are immediately flagged.

The app, and social media, has clearly shifted the way teams also strategize for the event, and even how they keep in touch with each other and their supporters.

Weather and GPS apps allow teams to change their plans to take advantage of ideal conditions, and avoid deteriorating ones.

“If we watch the radar and see rain coming toward an area where we expect to see a lot of different species, we might alter our route to get there after the rain,” Dunne said. “It’s all strategy. Is it worth it to change our plans? Do we skip some locations where we know there will be fewer species, but perhaps a rarer species, if we’re not sure the weather will hold up?”

Not all technology has proven beneficial for these birders. One epic fail? Night vision technology.

“All the top teams have tried and rejected night vision,” La Puma said. “Sure, you can see that there’s a bird in the tree, but it really just shows up as a green blob on night vision.”

That’s not exactly helpful for making a visual identification.

According to Dunne, the next frontier for the World Series of Birding will be sound amplification and recording.

“We’re still trying to figure out what’s legitimate and what’s not,” he said, with a laugh.

“Recording calls and identifying birds after the fact is definitely against the rules, even if it’s really tempting,” Dunne said. “But can you use sound equipment to make the distant calls sound clearer? I’m sure someone’s out there right now figuring that out.”

The rules are running to catch up with the ever-evolving technology.
